Congruent
They are said to be similar shapes and have the same interior angles.
If they are the same shapes but differ only in size, then they are SIMILAR shapes. Otherwise, they are simply different shapes.
... are said to be congruent.
similarity
similar shapes are shapes that have the same angles but are different sizes.
Organelles is a possible answer.
A figure that has both same size and shape is congruent.
Providing that they have the same angles they are said to be similar shapes
Cells are different shapes and sizes because they have different functions. The functions dictate the shapes and sizes.
No, the sizes and shapes of the continents do not directly correspond to the sizes and shapes of tectonic plates. Tectonic plates are larger and different in shape compared to the continents they contain. Continental plates can span multiple tectonic plates and vice versa.
No, they come in all shapes and sizes
For the same reason that humans come in different colors, shapes, and sizes. All birds are unique.
